Electric aviation is witnessing remarkable advancements as European start-up Maeve Aerospace unveils plans for an 84-seat hybrid-electric aircraft, the M80, while US-based Ampaire achieves a new endurance record with a 12-hour continuous flight for its demonstrator aircraft in California.
Maeve Aerospace, with dual headquarters in the Netherlands and Germany, envisions the M80 as a game-changer in the aviation industry. Designed to carry up to 84 passengers in a single-class layout or 76 in a two-class configuration, the M80 boasts a hybrid-electric powertrain, enabling electric-boosted take-off and climb. With a capacity for routes up to 800 nautical miles, the aircraft can achieve speeds of up to 400 knots at a maximum altitude of 35,000 feet.
The M80’s hybrid-electric engines and 10 battery packs aim for sustainability, compatible with various aviation fuels. The company, funded by private investors, the Dutch government, and the European Investment Council, aspires for entry into service by 2031. The aircraft targets certification to operate with 100% hydrogen-based power-to-liquid sustainable aviation fuel, promising over 95% reduction in CO2 emissions compared to similar-sized existing aircraft.
Maeve projects the M80 to have trip costs 25% lower than equivalent-sized regional jets and seat-mile costs over 20% below current-model turboprops. The innovative airframe design and high-performance propulsion anticipate a 40% reduction in fuel consumption compared to regional jets during cruise level flights.
Martin Nüsseler, CTO of Maeve, expressed optimism about the M80, stating, “To my knowledge, there are currently no alternatives in development that are equally sustainable, cost-effective, and match the operational needs of airlines and airports.”
In parallel, Ampaire, a US-based hybrid-electric manufacturer, achieved a milestone with a record 12-hour endurance flight in California. The twin-engine Cessna 337 Electric EEL covered 1,375 miles in a continuous circuit, setting a new benchmark in electric flight. Ampaire’s innovative AMP-H570 AMP Drive hybrid propulsion system, showcasing reductions of 50%-70% in fuel consumption and emissions, powers its Eco Caravan, a retrofitted Cessna 208B commuter plane.
Kevin Noertker, CEO of Ampaire, emphasized the groundbreaking nature of the mission, noting that their hybrid-electric solutions deliver unparalleled operating economics, endurance, and operational flexibility.
With orders and options for Cessna Caravan propulsion conversion kits, Ampaire is eyeing 2024 supplemental type certification from the US Federal Aviation Administration. The company’s success paves the way for larger retrofits, starting with the De Havilland Twin Otter, signaling a transformative era in electric aviation. The combined efforts of Maeve and Ampaire mark a significant leap forward, propelling the aviation industry into an era of sustainable and efficient electric flight.
